Compression of pistons, and rods.
Compression of pistons, and rods. I'll be buying my rods and pistons in the next week. I'm just going to have the block bored to clean it up and install new lower compression piston. What are in your opinion is the best compression? My goal is now going to be 600-650 RWHP, wherever I run out of fuel that's where we will stop with the power search. I plan on getting Mahle 9.5-1 .010 over pistons right now and forged eagle, oliver, ??? rods. I will buy the least expensive rods for the job that won't be questionable. Anyone have any thoughts. I will also be buying LPE's turbo/supercharger cam (LPE LS1 Camshafts 350-383-427, 208/230 .554/.546 w/1.7 rocker 121CL) for this combo. Is this the best compression and does anyone suggest a set of rods that would be reasonable for this job, $500 or under?

BTW, is this how everyone got their engine out? I fabricated a dolly for the k-member and used a tranny jack.

i would love to give you feedback, however i dont know enough about it. only thing i can think of, is with the cam from lpe, its either a supercharger cam or turbo cam. i think usually a supercharger cam is a reverse split, and turbo cam is normal split pattern. so depending on what kind of FI you go, that will help you decide which cam to get.
also, is your goal 600-650 rwhp on pump gas, meth, race fuel, or what? also, will this be daily driver, or just for the track? i would say, if you dont really plan on making too much more power then that, prob go with higher compression, anywhere from 8.5-9.0, and less timing.
1. you wont need as much psi to get there
2. if its a daily driver, you will have easier time to get moving in traffic, etc.
3.little bit better gas milage, but im sure thats prob not your concern.
just depends on what else your lookin to do, thats my input until someone else wants to chime in.

You honestly would probably be better off running a half point to full point lower in compression and run more boost. You'd be able to make more power and if you run the 9:1 slugs...you probably won't sacrifice much low end TQ or spool ability. Just my $.02.

Wish I would have.

No ****, god I hope so too. Most of you know that I've been looking for my first toy/project car and this really REALLY has me scared. Not much you can do about it but though
. I hope to HELL we can run ethanol in the next few years. That leads to another thread, guess I'll start that one but in which forum? LS1 Tech Stories

Obviously go with the longest rod you can to make it work. Let me know cause I have future plans of doing what you're doing, though maybe on an LS2 platform and maybe not @ a 4" storke. I've been rethinking that
